Chevron with techron

[Tatman48]

I have read where people say my 08 Yukon XL denali would run better on higher octane and Chevron techron. But we literally have no gas stations around me that sells it. Can an additive help

 

[iamdub]

Texaco is the same. Really, any top tier 89 or higher would be good. I can feel and hear a difference in mine with 91-93. Just don’t use Shell!

I have always use Chevron 91, if you have costco around not sure if they stock it in your area but they sell the techron fuel additive in 6pc box. I have used shell especially on long drive where sometimes no chevron close by, @iamdub what is your experience with shell that you stay away from that gas station? just curious thanks

Shakier idle, worse MPG and perceivable loss in power. This is comparing 91 because that was all I ran exclusively up until this past winter when I decided it was pointless during colder weather and with how little I was driving it. I would run my usual Valero, Chevron and Exxon and try a tank of Shell either because they were the cheapest or because I was on fumes and they seem to have stations everywhere one would be desperate for fuel. The difference was immediate and obvious to me. I also tend run my tank really low before refilling so whatever I had previously would be a very small, negligible amount mixed in.

I should probably include that my experience is with random Shells around my Gulf coast area and the mixtures are probably different up north.

Chevron with Techron 2 blocks down the street. Plus they take my Safeway gas points.

Anecdotal evidence, but when I was pulling logs for my custom tune, my tuner told me to use Mobil gas stations and never ever use Shell.

He tunes a lot of vehicles so I took him at his word.

James and I have both noted mpg losses from shell, as well, fwiw.

Don't know what your problems are with Shell, been running it in all 4 vehicles for the last 20 years, 3 of them have
clean tailpipes, all fuel injected and well maintained, with oil changes on schedule and tune ups. 2000 Tahoe Limited,
05 5.3L Sub and 05 Toyota Matrix

My 4th is 4 barrel carbureted, old hot rod 55 Chevy 210, hard to run clean tail pipes, all run strong with Shell, keeps combustion chambers clean along with spark plugs. I'd post pictures of tail pipes if I knew how, show me yours.

Well, I guess I've just been extremely lucky.

Frankly, in my last 20 years of driving, I can't remember a single instance of getting "bad gas" from a gas station. Shell, Mobil, Exxon, Marathon, Speedway, Costco, Sams, BP, and even no-name brands when on road trips in the middle of BFE.

I've also never had any fuel-related issues in my vehicles - clogged injectors, etc. I also don't run any additives either. Current stable of six vehicles includes on with 200k miles, and two with 100k miles.

Guess I should probably go out and buy some lottery tickets.

Oh, and I run only 91+ octane in my Denali.

Not a problem, per se. Just that my mpg drops at least 1, usually 2 mpg when I run shell vs mobil. I was a shell guy for a long time, as well. I'm not anymore.

Wrong octane from Shell 3 different stations locally.. might be the same owner as 87 oct was coming out of 91 pumps

same with Acro/BP 87 oct in the 91 pumps


that is considered getting bad gas


also a mobil station was skimming fuel(not pumping but the display was counting) for the first 1-4$ it was costing me an extra 1/2 to 1 gallon or so at that one station..

Did you read that they were putting out 87 in the 91 pumps? Because the few times I've put 87 in my Denali, there wasn't much of a noticeable difference.

Around where I am, the chevron stations are hardly ever visited, most sell like shit also, outdated items on shelf, just a dope smokers outlet store for pipes etc... overpriced equal to or higher than shell. I tried one that was a few years old, pretty clean on major road, within pulling out of the station, truck was popping, stammering, and cut down on power, yep got some water from the fuel, cleared out few miles later, but the chevron didnt seem to run well at all... granted could just be the station, but whatever. The shell around here runs ok, I think all the additives they put in screw with combustion cycles. Exxon/mobil same shit... Runs a bit better than shell for sure over shell and the chevron around here. Valero seems to do the job the best it seems for major station gas. NOW there is a kroger with a gas station on a very busy road here, sometimes they have the best gas, dont know where it comes from, BUT when they have it, my idle shakes go away, truck feels brand new again.

So find what works for you, I know winter blends and summer blends are very different and have effects on power and idle. Down here with humidity and dewpoints going 1 side to other, we get water in the gas and the ethanol just loves this weather.....

To answer the OP question on the additive, it works ok, its not enough concentration like what is blended in the gasoline from stations. 1 bottle for 15 gallons is about best ratio i can tell you... Best fuel additive I have played with was Royal Purple Max Atomizer. Best on the shelf ever. This is 91 octane valero, 25 mile freeway commute 65 to 75 with the royal purple.
